Metallics JRMB91 – Frequently Asked Questions

1) Will an 8-32 machine screw thread into a standard electrical device box or switch plate?
8-32 is the thread used on outlet boxes, device mounting ears, and cover plates, so the Metallics JRMB91 screw threads straight into that prep. It is a 32 threads-per-inch machine thread made to ANSI/ASME B1.1, which is the same thread form as the screws that ship with the box, just 2 inches long instead of the short factory screw.
2) Can I use these on a federally funded job with Buy American requirements?
No. The JRMB91 brass machine screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. For a job carrying domestic sourcing requirements you need a domestically produced fastener instead.
3) Are these brass screws solid brass, and does that matter for grounding or corrosion?
The JRMB91 screws are brass material, not plated steel. That is why they get specified for damp or corrosive locations and for bonding and grounding terminations where a non-ferrous, conductive fastener is wanted. Brass is softer than steel, so drive them with a properly fitting slotted blade and do not over-torque.
4) How far does the round head stand off the surface, and how wide is it?
The head measures 0.287 to 0.309 in. across and 0.107 to 0.12 in. high. That is a domed profile that sits on top of the surface rather than pulling flush, so it will not seat in a countersunk hole. If the hole is chamfered for a flush finish you want a flat head screw instead.
5) Are these Metallics machine screws made to a dimensional standard I can put on a submittal?
Head and drive dimensions follow ASME B18.6.3 and the thread follows ANSI/ASME B1.1. Those are the two standards a spec writer looks for on a slotted round head machine screw, and they are what lets the part be swapped with any other B18.6.3 round head of the same 8-32 x 2 size.
6) How are these 8-32 brass screws packaged and what is the smallest quantity I can order?
They come in a jar, 100 screws, and 100 is the order minimum. So a single order line gets you a jar of 100 rather than loose pieces.
7) What trades normally stock 8-32 x 2 in. brass round head machine screws?
They are carried for electrical, plumbing, heating and air conditioning work. In practice that means device and plate mounting, fixture and canopy attachment, and panel or enclosure hardware where a brass fastener is wanted. MRO and facilities crews keep a jar on the truck because 8-32 is the one machine thread that shows up on nearly every box and cover.
8) How much does a jar of these 8-32 x 2 in. brass screws weigh?
A jar of 100 runs 1.16 lbs. Useful if you are building a kit list or watching freight weight on a bulk fastener order.
